DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

Turning to FIG. 1, a first embodiment of portable electronic device case 10 is depicted in flat-open disposition to include device display receiving portion 12, device keyboard receiving portion 14, spine portion 15 therebetween, first side 16, second side 17, first end 18, and second end 19. Portable electronic device case 10 is made of a semiflexible plastic piece 20 that is molded as one piece to include first portion 20 a, second portion 20 b, third portion 20 c, fourth portion 20 d, fifth portion 20 e, sixth portion 20 f, and seventh portion 20 g. First portion 20 a and third portion 20 c intersect at first corner 22 a. First portion 20 a and second portion 20 b intersect at second corner 22 b. Fifth portion 20 e and seventh portion 20 g intersect at third corner 22 c. Sixth portion 20 f and seventh portion 20 g intersect at fourth corner 22 d. First through seventh portions 20 a-20 g and first through fourth corners 22 a-d of semiflexible plastic piece 20 are designated herein solely for illustration purposes regarding the Figures rather than being actual separate and distinct pieces of portable electronic device case 10 since semiflexible plastic piece 20 is molded as one piece.

Semiflexible plastic piece 20 can be a soft, flexible, plastic material such as thermoplastic polyurethane, thermoplastic elastomers (TPE), silicone or other soft plastic material, which provides shock absorption and textured surfaces for handling qualities. Semiflexible plastic piece 20 is also located in spine portion 15 and along first side 16, second side 17, first end 18, and second end 19, which are areas where portable electronic device case 10 would more likely first impact a hard surface if accidentally dropped and are also likely areas that would receive hand contact when held to allow for grip assistance due to a desirably enhanced tactile quality of semiflexible plastic piece 20. Cutouts 24 have a crumple-like character for first through fourth corners 22 a-d that enhance shock absorption qualities of semiflexible plastic piece 20 in these locations.

Portable electronic device case 10 has semirigid plastic material 26 in first semirigid plastic panel 26 a and second semirigid plastic panel 26 b. Semirigid plastic material can be such as polycarbonate and can be transparent, translucent, semi-transparent, semi-translucent, opaque, or fully solid. First channel 28 a is positioned between semiflexible plastic piece 20 and first semirigid plastic panel 26 a. First channel 28 b is positioned between semiflexible plastic piece 20 and second semirigid plastic panel 26 b.

Portions of hinge 30 include cuts 32 and stops 34 along with the flexible nature of semiflexible plastic piece 20 that make up fourth portion 20 d, which constitutes the spine portion 15 of portable electronic device case 10 so consequently serves a flexibility role for hinge 30. Referring now to FIG. 2, hinge 30 further includes ribs 36 running along the spine of portable electronic device case 10 to provide cushion/protection to spine portion 15. First through fourth corners 22 a-d include cutouts 38 for further shock absorbing qualities. First semirigid plastic panel 26 a and second semirigid plastic panel 26 b appear to be shaped differently than what is shown in FIG. 1 because there is more of semiflexible plastic piece 20 overlaid on to first semirigid plastic panel 26 a and second semirigid plastic panel 26 b on the exterior compared with the interior of portable electronic device case 10. Turning to FIG. 3, portable electronic device case 10 is shown in angled-open disposition with an exemplary portable electronic device shown as a laptop with a display portion and a keyboard portion hingedly disposed therebetween. Device display receiving portion 12 and device keyboard receiving portion 14 of the semiflexible plastic piece 20 are shown sized and shaped to receivably couple along edges of the display portion and of the keyboard portion of the exemplary portable electronic device, respectively. The semiflexible plastic piece 20 is shown to have flexibility sufficient for the spine portion 15 to accommodate hinged disposition between the display portion and the keyboard portion of the exemplary portable electronic device. Referring now to FIG. 4, portable electronic device case 10 is shown in closed disposition in an exterior perspective view. Turning to FIG. 5, portable electronic device case 10 is shown in closed disposition in an exterior top plan view.

Referring now to FIG. 6, portable electronic device case 10 is shown in cross-sectional side-elevational view along 6-6 cut line of FIG. 4 and FIG. 5 showing inner space bounded by interior portions of portable device case in closed disposition. Two opposite facing stops 34 are depicted as providing support to prevent shape collapse of the semiflexible plastic piece 20 in their vicinity. Turning to FIG. 7, portable electronic device case 10 is shown in cross-sectional side-elevational view along 6-6 cut line of FIG. 4 and FIG. 5 showing inner space bounded by interior portions of portable device case in closed disposition.

Referring now to FIG. 8A, portable electronic device case 10 is shown in an enlarged cross-sectional side-elevational view of a dashed-oval-designated “8A” portion of portable device case of FIG. 6 in closed disposition. Shown is first overmold portion 40 a of fourth portion 20 d of semiflexible plastic piece 20 that overlaps first overmold portion 42 a of first semirigid plastic panel 26 a of semirigid plastic material 26 at first interface 44 a. First channel 28 a is formed by first ridge 46 a of first semirigid plastic panel 26 a, by a portion of first overmold portion 40 a, and by a portion of first overmold portion 42 a. Also shown is second overmold portion 40 b of fourth portion 20 d of semiflexible plastic piece 20 that overlaps second overmold portion 42 b of second semirigid plastic panel 26 b of semirigid plastic material 26 at second interface 44 b. Second channel 28 b is formed by second ridge 46 b of second semirigid plastic panel 26 b, by a portion of second overmold portion 40 b, and by a portion of second overmold portion 42 b.

Turning to FIGS. 8B and 9, further views of portable electronic device case 10 are shown involving first and second overmold portions 40 a and 40 b, first and second overmold portions 42 a and 42 b, overlapping each other at first and second interfaces 44 a and 44 b, respectively. FIG. 8B is an enlarged cross-sectional side-elevational view of a dashed-circle-designated “8B” portion of portable device case of FIG. 6, which is a cross-sectional side-elevational view along 6-6 cut line of FIG. 4 and FIG. 5 showing inner space bounded by interior portions of portable device case in closed disposition. FIG. 9 is an enlarged cross-sectional side-elevational view of a dashed-circle-designated “9” portion of portable device case of FIG. 7, which is a cross-sectional side-elevational view along 7-7 cut line of FIG. 4 and FIG. 5 showing inner space bounded by interior portions of portable device case while in its closed disposition.

Further aspects of portable electronic device case 10 include following: second primary material 26 when translucent or transparent allows to be seen through to provide clear access to allow scanning for asset tags without need for opening up portable electronic device case 10. Semiflexible plastic piece 20 can have a hardness range of between 55-85 degrees. During molding, after the first semirigid plastic panel 26 a and the second semirigid plastic panel 26 b are formed, the semiflexible plastic piece 20 can be formed to overlap the first semirigid plastic panel 26 a and, the second semirigid plastic panel 26 b to be “over-molded” or “co-molded” with the first semirigid plastic panel 26 a and the second semirigid plastic panel 26 b. More material is shown to be located at corners of portable electronic device case for impact protection in case of accidentally drops.

For instance, steps of a manufacture process can include 1) tool/create metal mold (e.g. steel mold), 2) heat semirigid plastic material 26 (e.g. polycarbonate) to be a fluid to fill a first portion of the metal mold, 3) wait for semirigid plastic material 26 plastic to solidify to form the first semirigid plastic panel 26 a and the second semirigid plastic panel 26 b of the portable electronic device case 10, 4) heat semiflexible plastic material (e.g. thermoplastic elastomers (TPE), thermoplastic polyurethane, or silicone) to be a fluid to fill a second portion of the metal mold, 5) wait for the semiflexible plastic material 26 to solidify to form the semiflexible plastic piece 20 to partially overlap and to be molded with the first semirigid plastic panel 26 a and the second semirigid plastic panel 26 b of the portable electronic device case 10 so that the softer semiflexible plastic piece 20 forms around edges of the first semirigid plastic panel 26 a and the second semirigid plastic panel 26 b for shock absorptive protection as well as forming spine portion 15 that transitions from device display receiving portion 12 to device keyboard receiving portion 14. Consequently the semiflexible plastic piece 20 is molded together with the first and second semirigid plastic panels 26 a, 26 b to partially overlap with them and to form first and second channels 28 a, 28 b therebetween and overall to form the single-molded dual-material portable electronic device case 10.

Turning to FIG. 10, shown is a first exterior perspective view of a second embodiment of portable device case 110 to include first case section 112, which is to house a display portion of an electronic device and second case section 114, which is to house a keyboard portion of an electronic device. First case section 112 and second case section 114 can be attached to an electronic device separately as two pieces to the electronic device's keyboard and display sections to rotate 360 degrees to go into tablet mode if the electronic device is capable of such rotation. Portable electronic device case 110 further includes first side 116, second side 118, first end 120, and second end 122.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.
